CAUTION: Safety Instructions Use the following safety guidelines to help ensure your own personal safety and to help protect your computer and working environment from potential damage. General Do not attempt to service the computer yourself unless you are a trained service technician. Always follow installation instructions closely. If you use an extension power cable with your AC adapter, ensure that the total ampere rating of the products plugged in to the extension power cable does not exceed the ampere rating of the extension cable. Do not push objects into air vents or openings of your computer. Doing so can cause fire or electric shock by shorting out interior components. Do not store your computer in a low-airflow environment, such as a carrying case or a closed briefcase, while the computer is turned on. Restricting airflow can damage the computer or cause a fire. Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug. Place the AC adapter in a ventilated area, such as a desk top or on the floor, when you use it to run the computer or to charge the battery. Do not cover the AC adapter with papers or other items that will reduce cooling; also, do not use the AC adapter inside a carrying case. The AC adapter may become hot during normal operation of your computer. Use care when handling the adapter during or immediately after operation. Do not allow your portable computer to operate with the base resting directly on exposed skin for extended periods of time. The surface temperature of the base will rise during normal operation (particularly when AC power is present). Allowing sustained contact with exposed skin can cause discomfort or, eventually, a burn. Do not use your computer in a wet environment, for example, near a bath tub, sink, or swimming pool or in a wet basement. System Information Guide 5
www.dell.com support.dell.com CAUTION: Safety Instructions (continued) If your computer includes an integrated or optional (PC Card) modem, disconnect the modem cable if an electrical storm is approaching to avoid the remote risk of electric shock from lightning via the telephone line. To help avoid the potential hazard of electric shock, do not connect or disconnect any cables or perform maintenance or reconfiguration of this product during an electrical storm. Do not use your computer during an electrical storm unless all cables have been disconnected and the computer is operating on battery power. If your computer includes a modem, the cable used with the modem should be manufactured with a minimum wire size of 26 American wire gauge (AWG) and an FCCcompliant RJ-11 modular plug. Before you open the memory module/mini PCI card/modem cover on the bottom of your computer, disconnect all cables from their electrical outlets and disconnect the telephone cable. If your computer has both a modem RJ-11 connector and a network RJ-45 connector, which look alike, make sure you insert the telephone cable into the RJ-11 connector, not the RJ-45 connector. PC Cards may become very warm during normal operation. Use care when removing PC Cards after their continuous operation. Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances. Power Use only the Dell-provided AC adapter approved for use with this computer. Use of another AC adapter may cause a fire or explosion. Before you connect the computer to an electrical outlet, check the AC adapter voltage rating to ensure that the required voltage and frequency match the available power source. To remove the computer from all power sources, turn the computer off, disconnect the AC adapter from the electrical outlet, and remove any battery installed in the battery bay or module bay. 6 System Information Guide
To help prevent electric shock, plug the AC adapter and device power cables into properly grounded power sources. These power cables may be equipped with 3-prong plugs to provide an earth grounding connection. Do not use adapter plugs or remove the grounding prong from the power cable plug. If you use a power extension cable, use the appropriate type, 2-prong or 3-prong, to mate with the AC adapter power cable. Be sure that nothing rests on your AC adapter s power cable and that the cable is not located where it can be tripped over or stepped on. If you are using a multiple-outlet power strip, use caution when plugging the AC adapter s power cable into the power strip. Some power strips may allow you to insert the plug incorrectly. Incorrect insertion of the power plug could result in permanent damage to your computer, as well as risk of electric shock and/or fire. Ensure that the ground prong of the power plug is inserted into the mating ground contact of the power strip. Battery CAUTION: Safety Instructions (continued) Use only Dell battery modules that are approved for use with this computer. Use of other types may increase the risk of fire or explosion. Do not carry a battery pack in your pocket, purse, or other container where metal objects (such as car keys or paper clips) could short-circuit the battery terminals. The resulting excessive current flow can cause extremely high temperatures and may result in damage to the battery pack or cause fire or burns. The battery poses a burn hazard if you handle it improperly. Do not disassemble it. Handle a damaged or leaking battery pack with extreme care. If the battery is damaged, electrolyte may leak from the cells and may cause personal injury. Keep the battery away from children. Do not store or leave your computer or battery pack near a heat source such as a radiator, fireplace, stove, electric heater, or other heat-generating appliance or otherwise expose it to temperatures in excess of 60ºC (140ºF). When heated to excessive temperatures, battery cells could explode or vent, posing a risk of fire. Do not dispose of your computer s battery in a fire or with normal household waste. Battery cells may explode. Discard a used battery according to the manufacturer s instructions or contact your local waste disposal agency for disposal instructions. Dispose of a spent or damaged battery promptly. System Information Guide 7
www.dell.com support.dell.com Air Travel CAUTION: Safety Instructions (continued) Certain Federal Aviation Administration regulations and/or airline-specific restrictions may apply to the operation of your Dell computer while you are on board an aircraft. For example, such regulations/restrictions may prohibit the use of any personal electronic device (PED) that has the capacity for intentional transmission of radio frequency or other electromagnetic signals while on an aircraft. In order to best comply with all such restrictions, if your Dell portable computer is equipped with Dell TrueMobile or some other wireless communication device, please disable this device before you board the aircraft and follow all instructions provided by airline personnel with regard to such device. Additionally, the use of any PED, such as a portable computer, may be prohibited in aircraft during certain critical phases of flight, for example, takeoff and landing. Some airlines may further define the critical flight phase as any time the aircraft is below 3,050 m (10,000 ft). Please follow the airline s specific instructions as to when the use of a PED is allowed. EMC Instructions Use shielded signal cables to ensure that you maintain the appropriate electromagnetic compatibility (EMC) classification for the intended environment. For parallel printers, a cable is available from Dell. If you prefer, you can order a cable from Dell at its worldwide website at www.dell.com. Static electricity can harm electronic components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer s electronic components, such as a memory module. You can do so by touching an unpainted metal surface on the computer s input/output panel. 8 System Information Guide
When Using Your Computer Observe the following safe-handling guidelines to prevent damage to your computer: When setting up the computer for work, place it on a level surface. When traveling, do not check the computer as baggage. You can put your computer through an X-ray security machine, but never put your computer through a metal detector. If you have the computer checked by hand, be sure to have a charged battery available in case you are asked to turn on the computer. When traveling with the hard drive removed from the computer, wrap the drive in a nonconducting material, such as cloth or paper. If you have the drive checked by hand, be ready to install the drive in the computer. You can put the hard drive through an X-ray security machine, but never put the drive through a metal detector. When traveling, do not place the computer in overhead storage compartments where it could slide around. Do not drop your computer or subject it to other mechanical shocks. Protect your computer, battery, and hard drive from environmental hazards such as dirt, dust, food, liquids, temperature extremes, and overexposure to sunlight. When you move your computer between environments with very different temperature and/or humidity ranges, condensation may form on or within the computer. To avoid damaging the computer, allow sufficient time for the moisture to evaporate before using the computer. NOTICE: When taking the computer from low-temperature conditions into a warmer environment or from high-temperature conditions into a cooler environment, allow the computer to acclimate to room temperature before turning on power. When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. As you pull out the connector, keep it evenly aligned to avoid bending any connector pins. Also, before you connect a cable make sure both connectors are correctly oriented and aligned. Handle components with care. Hold a component such as a memory module by its edges, not its pins. When preparing to remove a memory module from the system board or disconnect a device from the computer, turn off the computer, disconnect the AC adapter cable, remove any battery installed in the battery bay or module bay, and then wait 5 seconds before proceeding to help avoid possible damage to the system board.
